The core region might be a name for the area inside the meteorite, but it was more than just a simple area. It was a world of its own.
That was why the laws and the environment were so different than Earth.
The sky was one such difference. There were no clouds, moon, stars, etc. Instead, it was filled with dimmed dots of light; the dimness signifying night time.
The soft, transparent dots of light reflected on the ethereal Pond of Lust, enhancing its beauty. Fragrant winds passed through the pond, creating spellbinding ripples in which the reflections twisted in a mesmerizing manner.
The pond was an absolutely beautiful sight, and one couldn't help but feel a strong urge to step inside, and participate in the magical experience the pond promised.
